Description

IO object を freeze すると、inspect や fileno が RuntimeError になるんですが、
これはよろしくないんじゃないかと思います。

% ./ruby -e 'f = open("."); f.freeze; p f'       
-e:1:in `inspect': can't modify frozen File (RuntimeError)
    from -e:1:in `p'
    from -e:1:in `<main>'
% ./ruby -e 'f = open("."); f.freeze; p f.fileno'
-e:1:in `fileno': can't modify frozen File (RuntimeError)
    from -e:1:in `<main>'
% ./ruby -v
ruby 2.2.0dev (2014-05-27 trunk 46150) [x86_64-linux]

あるいは、なにか理由がありましたっけ?
